Product description
Steel grit GL120 is a type of Micro Steel Grit. Steel grit is made by heating and quenching high carbon or alloy scrap steel, then grinding the secondary quenching steel grit with specialized machinery, and finally screening and classifying it. The GL series of steel grit is the hardest steel grit series, and GL120 has a blue color compared to other classifications. It is a commonly used product of China Precision Steel Grit. The shape of steel grit is irregular, with irregular edges, high hardness, strong toughness, impact resistance, and can be reused multiple times. A type of china pretreatment steel grit. When used for sandblasting, the contact surface with the object is sharper and more conducive to cleaning the surface. Specially suitable for pre-treatment of steel surfaces to remove oxide scales and significantly improve the surface adhesion of coatings after coating.
The process of generating steel grit is roughly shown in the following figure：

Product Specification grade
Product Features
The GL120 series of steel grit has the lowest hardness in the steel grit series, ranging from 56-60HRC. It has high density but is rare, good metallographic structure, superior mechanical properties, good toughness and resistance to breakage and fatigue, high reuse rate, and low consumption. Steel grit can be widely used in industries such as casting, stone processing, steel structures, shipbuilding, aviation, die-casting, locomotives, containers, etc., depending on the size of the device.It is a commonly used product of China Precision Steel Grit.
Product differentiation
Product size
The size of steel grit GL120 is 0.2 mm, which is selected after grinding. The size of steel grit GL120 is relatively large in the steel grit series. Because different application fields have different requirements for the specifications of steel sand. For example, some precision machining fields require fine-grained steel grit, while some cleaning and rust removal fields require coarse-grained steel grit.
Product Color
The color of steel grit GL120 is blue among all series of steel grit. GL series steel grit is formed by non tempering, commonly referred to as blue steel grit. This is a significant feature that distinguishes GP series steel grit from other series of steel grit.
Product hardness
The GL series of steel grit has the highest hardness among steel grit, ranging from 56-60HRC. Therefore, its characteristics include fast processing speed of workpieces, a more glossy surface, but faster crushing and relatively reduced usage time.
Product application
The following are common uses of GL120 series steel grit
1.Metal surface treatment
Rust removal: Steel grit can remove rust from metal surfaces through shot blasting or sandblasting. For example, in the maintenance of large metal structures such as ships, bridges, and petrochemical equipment, steel grit can peel off the rust layer from the metal surface, restoring its smoothness and providing a good foundation for subsequent protective coating construction.
Surface cleaning and strengthening: For newly produced metal parts such as automotive and mechanical components, steel grit can be used to clean the surface of oxide scale, dirt, and impurities. Simultaneously improve its hardness and fatigue resistance.
2.Construction industry
Stone cutting and polishing: Steel sand is an important abrasive for cutting and polishing in the process of stone processing. It can be used to cut various natural stones such as marble and granite. Steel sand can smooth out the rough parts of the stone surface and improve the glossiness of the stone surface.
Concrete surface treatment: In concrete construction, steel sand can be used to treat the concrete surface, increase the roughness of the concrete surface, and improve the adhesion between the concrete and subsequent coatings (such as epoxy floor paint) or other materials (such as tiles).
3.Foundry industry
Core making and molding materials: When casting sand molds and cores, steel sand can be added as an additive to the molding sand to improve the strength and breathability of the sand molds and cores. Due to its high hardness and high temperature resistance, steel sand can withstand the high-temperature impact of molten metal during the casting process, preventing deformation or damage to the sand mold and core during pouring, thereby ensuring the quality and dimensional accuracy of castings.
4.Spray painting industry
Increasing coating adhesion: Before spraying paint, powder coating, and other coatings, pre treating the substrate material with steel grit can increase the roughness of the substrate surface, allowing the coating to better adhere to the material surface.
How to distinguish the quality of steel grit?
Firstly, we can see from the surface of the steel grit that good steel grit has a smooth surface, no impurities, and a relatively uniform blue color, while poor quality steel grit may have impurities on its surface and a dull color. Secondly, we can gently tap the steel sand with our fingers. Good steel sand produces a crisp and pleasant sound, while poor quality steel sand produces a dull sound. In addition, we can use steel grit to polish iron parts. Good steel grit can quickly polish iron parts to make their surfaces smooth, while poor quality steel grit cannot achieve this effect.
